Fig 2. Collagen structures within the atherosclerotic aortic sinus.

Frozen sections of both control mice and Dagla-deficient mice were stained using haematoxylin and direct red to visualise collagen structures. Microphotographic pictures were taken using bright field microscopy (A, D), polarisation microscopy (B, E), or a combination of both (C, F). No differences were seen in amount and distribution of collagen fibers between control mice (A-C) and Dagla-deficient mice (D-F). Scale bar, 200 μm. Cre, cyclisation recombination; Dagla, diacylglycerol lipase α; fl, flanked by loxP.
